Water has an incredible capacity to fuck up WE's terrain capabilities: if you do anything unorthodox it's quite common to have these sort of bugs emerge. I'm not sure of any real way to combat them except careful restorative work, often by wiping a block with a large brush and then slowly re-adding the desired features.
Lol :)

FYI, I consider it a good idea not to alter or eliminate your original question in threads such as these. That way, if a future forum-goer finds this thread while searching the forums for an answer to their similar problem, you may save them having to ask about it at all.
